A standard structure for storing data in any programming language is an array. Whereas individual variables can hold single entities, such as a number, date, or string, arrays can hold sets of related data.

You may need to use two subscripts to identify tabular data, where data are arranged in rows and columns. To define a two-dimentional array or table, the Dim statement specfies the number of rows and columns in the array. The row is horizontal and the column is vertical.

List Index property is used to determine the array subscript. List Index property holds the position or index of the selected item in the list. We could then use this index with one minor change to access the group total. List index property always begins with 0.

Sometimes, array are referred to as tables or subscripted variables, all referenced by the same name. When we use a control array, the individual controls are referenced as optCoffee(0) or optCoffee(1). The same notation is used with variable arrays. Therefore, in an array for storing names we may have strName(0), strName(1), strName(2) and so on.

(Dynamic-linked library) In programming, a type of LIBRARY file that becomes LINKED to a program that uses it only temporarily when the program is loaded into memory or executed, rather than being permanently built-in when the program is COMPILED. The same DLL may therefore be shared by many different programs, rather than each program having to contain its own copy; this saves on memory usage and potentially simplifies the updating of programs.

This phrase has two meanings. Compile time can refer to how long it takes to compile a given program (see the entry above). The compile time for a program depends on how long and complicated the program is, the speed of the computer, and the quality of the compiler.

To hold the internal data of our class create private variables in the general declaration of the class modules. Then we have to deign which properties we want to write access. We can decide these things using property get and property let procedures.

Declaring variables means naming the variable and specifying their data types, that is declaration statements establish our project’s variables and constants give them names, and specify the data type they will hold.

1. You can bound data to data bound controls like Labels, Text Boxes, Checkbox. If you don?t want user to change the data you use Label control, where user can only view the data else you can use Text boxes.

1. Two handy properties of the record set are BOF (beginning of file) and EOF (end of file). The BOF property is automatically set to true when the record pointer is before the first record in the record set.
